One idea for decorating an antique flower vase is to wrap it in bubble wrap before placing it on the table as a centerpiece, notes Real Simple. To make the bubble wrap more festive, users can coat it with acrylic paint.
Another idea is to fill a glass antique vase with balloons instead of flowers to make a party more lively. To get the balloons to fit inside, gauge the size of the vase and fill enough balloons accordingly with an air pump. An old glass vase can also receive a touch of color by wrapping a couple of multi-colored rubber bands around it, says Real Simple. To add more creativity to this project, overlap the rubber bands.
